A hypertonic saline enema draws fluid from body tissues into the bowel. The concentrated solution also acts as a local irritant on the mucous membranes. A retention enema lubricates and softens the stool. A tap water and normal saline solution has a non-irritating effect on the rectum but moistens the stool.
